ABSTRACT

Background: This study aimed to investigate human papillomavirus (HPV) type prevalence in our region and the relationship between uterine cervical HPV types and squamous cell carcinoma (SCC)/intraepithelial lesions. Methods: HPV test results were obtained from patient file archives of the Gynecology and Obstetrics Clinic. Pathology report results were obtained from the digital records of the Pathology Laboratory and the patient file archives of the Gynecology and Obstetrics Clinic in 2018. Results: The most frequently detected was HPV16 (29.2%), followed by HPV51 (13.1%), HPV56 (11%), HPV31 (9.2%), HPV52 (8.4%), and HPV68 (8.2%). HPV16 was positive in 50% of patients diagnosed with SCC, 54.9% of patients with HSIL, 27% of patients with LSIL, and 25% of cases diagnosed as benign (P<0.001). HPV18 was positive in 25% of patients diagnosed with SCC, 11% of patients with HSIL, 4.7% of patients with LSIL, and 5.2% of cases diagnosed as benign (P=0.019). Conclusion: The most frequent hrHPV genotype was HPV16, followed by HPV51, HPV 56, and HPV 31. There is an increase in the frequency of HPV51 and HPV56. HPV51, not included in HPV vaccines and is the second most frequent, should be included in these vaccines. In addition, although the frequency of HPV18 has decreased, HSIL and SCC generation is still high together with HPV16.

ABSTRACT

PURPOSE: The aim was to compare the density of ghrelin-expressing cells (GECs) in morbid obese patients with or without intestinal metaplasia (IM). MATERIALS AND METHODS: The study included 48 patients out of 244 who underwent laparoscopic sleeve gastrectomy between 2015 and 2019. IM was detected in the sleeve gastrectomy specimens of 24 of these 244 patients. The study group consisted of all of the patients with IM. It was a case matched study. Matching factors were age and gender. Ghrelin was stained with a Leica semiautomatic immunohistochemical-staining machine. Stained preparations with ghrelin were subjected to light microscopic examination. RESULTS: The number of GECs in cases with IM was significantly lower than the cases without IM (p = 0.001). The number of GECs was significantly higher in cases with chronic inactive superficial gastritis than cases with chronic active superficial gastritis (p = 0.033). CONCLUSION: We found that there was a decrease in the number of GECs in the corpus and fundus of the stomach in cases with gastric IM as a contribution to the literature. IM cause a decrease in the number of GECs in the gastric oxyntic glands. In addition, chronic active superficial gastritis is also associated with a decrease in the number of GECs. We can say that the common feature of all of these factors may be gastric mucosal damage. Consequently, damage to the gastric mucosa appears to reduce the number of GECs.

ABSTRACT

The association between amyloidosis and collagen vascular diseases, such as rheumatoid arthritis (RA) is well-documented. Amyloid goiter is an extremely rare pathologic condition caused by a massive amyloid infiltration of the thyroid tissue. Our patient had been diagnosed with RA 20 years ago and was on hemodialysis for 7 years. He was assessed for decreased appetite, dysphagia, and nausea during the hemodialysis. On physical examination, the thyroid was diffusely enlarged with multiple nodules. He was biochemically euthyroid. Ultrasound of the thyroid gland showed multinodular goiter. A total thyroidectomy was performed. Histopathological examination showed dilated follicles surrounded by abundant homogeneous substance that stained positive with Congo red. The patient was reported as amyloid goiter. Complaints of the patient improved after the surgery. In the literature, amyloid goiter with RA in a hemodialysis patient is very rare. Amyloid goiter should be considered if there is a rapid thyromegaly causing pressure symptoms in the background of any disease with chronic inflammation.

ABSTRACT

Background Routine application of fine needle aspiration cytology (FNAC) has decreased unnecessary referral of thyroid nodules for surgical treatment and has also increased the cancer rates found in surgery materials. Success of thyroid FNAC depends on skilled aspiration, skilled cytological interpretation and rational analysis of cytological and clinical data. The aim of this study was to determine the diagnostic accuracy rates of thyroid FNAC results obtained in our institution. Methods The data from FNAC and thyroidectomy reports of patients presenting with goiter and who had been evaluated from 1st January 2014 to 1st March 2018 were used. There were 149 patients in total who had undergone thyroidectomy following FNAC. The Bethesda System for Reporting Thyroid Cytology was used in all cytological diagnoses. Results The sensitivity of thyroid FNAC for malignant cases was 57.89%, specificity was 88.10%, false-positive rate was 11.90%, false-negative rate was 42.11%, positive predictive value was 52.38%, negative predictive value was 90.24% and accuracy rate was 82.52%. "Focus number" variable was detected as the factor that affected the accurate prediction of FNAC and thyroidectomy results by the pathologist. Conclusions This study showed that there was a moderate conformity between thyroid FNAC and thyroidectomy cyto-histopathological diagnosis in malignant cases. As two or more nodules have a negative effect on the physician's diagnosis of malignant nodules, we think that a more sensitive approach is needed in the determination of these cases. Sampling defects may affect this non-matching.

ABSTRACT

AIM: The aim of this study was to investigate the correlation between histopathologic findings detected in laparoscopic sleeve gastrectomy (LSG) specimens and excess weight loss percentages (%EWL) and excess BMI decrease percentages (%EBL). METHODS: Patients who underwent LSG in the hospital's Gastroenterological Surgery Department between the years 2013 and 2018 and who completed 1 year of follow-up were involved in the study. Patients whose 6th month and 12th month BMI were unknown were excluded from the study. Clinical and pathologic data of the cases were obtained from the automation system of the hospital. RESULTS: As a result of comparison among diagnosis groups, it was detected in the histopathologic analysis that the 12th month mean %EWL measurement was higher in the inactive stomach diagnosis group. In the comparisons among intestinal metaplasia (IM) groups, it was seen that 6th month %EWL and %EBL and 12th month %EWL and %EBL measurements were higher in the group without IM. Age, baseline BMI and active gastritis incidence in histopathologic analysis have a negative effect on weight loss. CONCLUSIONS: A correlation of histopathologic changes in morbid obese patients with weight loss after bariatric surgery was asserted in this study. Operating on younger patients with lower BMI and inactive gastritis with the LSG method could contribute to achieving more successful results. Prospective research studies are necessary within this context.

ABSTRACT

INTRODUCTION: Histological changes of psoriasis include invasion of neutrophils into the epidermis and formation of Munro abscesses in the epidermis. Neutrophils are the predominant white blood cells in circulation when stimulated; they discharge the abundant myeloperoxidase (MPO) enzyme that uses hydrogen peroxide to oxidize chloride for killing ingested bacteria. AIM: To investigate the contribution of neutrophils to the pathogenesis of psoriasis at the blood and tissue levels through inducible nitric oxide synthase (iNOS) and MPO. MATERIAL AND METHODS: A total of 50 adult patients with a chronic plaque form of psoriasis and 25 healthy controls were enrolled to this study. Serum MPO and iNOS levels were measured using ELISA method. Two biopsy specimens were taken in each patient from the center of the lesion and uninvolved skin. Immunohistochemistry was performed for MPO and iNOS on both normal and psoriasis vulgaris biopsies. RESULTS: While a significant difference between serum myeloperoxidase levels were detected, a similar statistical difference between participants in the serum iNOS levels was not found. In immunohistochemistry, intensely stained leukocytes with MPO and intensely staining with iNOS in psoriatic skin was observed. CONCLUSIONS: Neutrophils in psoriasis lesions are actively producing MPO and this indirectly triggers the synthesis of iNOS. Targeting of MPO or synthesis of MPO in the lesion area may contribute to development of a new treatment option.

ABSTRACT

A 38-year-old man was admitted to our clinic with an enlarging right scrotal mass that had been present for 7 years. Right radical inguinal orchiectomy was performed and a histopathological diagnosis confirmed a very rare case of cholesterol granuloma of the paratesticular tissue. It can be very difficult to preoperatively distinguish testicular tumours from cholesterol granulomas of the testis or epididymis. Cholesterol granuloma should be kept in mind in patients with large and non-tender scrotal masses.
